SH EET-M ETAL CAN.

SPECIFICATION forming part ef Lettere Patent No. 260,432, dated July 4, 1882.

Application nieu April 1s, 1882. (Ne model.)

To all whom it may concern Be it known that I, FRANCIS A. WALSH, of Chicago, in the ,county of Cook and State of Illinois, have inyented certain new and useful Improvements in Sheet-Metal Cans 5 and I hereby declare the following to be a full, clear,

and exact description thereof, which'will en-` able others skilled in the art to' which my invention appertains to make and use the same, reference being had to the accompanying drawings, which are made a part hereof, and in whichf` Figure 1 represents a vertical sectional elevation of a sheet-metal can embodying my invention, and showin g the slip-cover applied on the outside of the body'of the can. Fig. 2 represents the slip-cover as applied Within the body of the can, and Fig. 3 represents a modiication of the annular ring. Y

Like letters of reference indicate like parts.

My invention relates to that class of cans employed for packing and transporting liquid paints and paint-colors; and myinvention consists in the construction and combination ofl the Several parts, as hereinafter described and claimed.

In the drawings, A represents the body of the can, and a the bottom, which is united to the body by means of the ordinary soldered 3o joint.

B represents acountersunk fixed top, which is formed or stamped from thin or soft sheet m,e,talcloth,for-paper, and so formed that the outer diameter of the shoulder or wall of the depression or countersink d shall correspond to and t within the opening of the body of the can, andthe shoulder or wall thereof shall be parallel to the body A ot' the can and of a depth sufficient to receive the flange e of the slip-cover C.

I have learned byexperience that in attaching the thin or soft xed cover to the body of the can the pressure of the mandrel necessary to hold said cover iu position during the operation ot se'aming is apt to depress the cover and drawv it out of position, and thereby form an imperfect joint. To obviate this objection I place over the fixed cover and the .top ofthe body ofthe can a sheetmeta1 annular ring, D, and attach it and the fixed cover to the body ot the can by means of seamin g. The inner wall of the annular ring maybe vertical, and with a lateral projecting burr or ange, as shown at h, Figs. lor 2, or with its inner Wall inclined or beveling, as shown at h', Fig. 3. In either case the inner opening, l, of the ring D is smaller than the mouth Z and of less diameter than the countersunk Ixed top B, so that in the process of uniting the parts together by seaming the mandrel does not pass through the opening l, but rests upon the ange h or against'its inclined wall 7L', and is supported thereby and so as not to come in'contact with the thin or soft fixed cover.

After the can has been filled with the desired contents and the outer edge of the countersunk fixed cover B and annular ring D are united to the body of the can, as shown and described, the Slipcover C is applied to the body of the can and over the fixed cover B, either outside ofthe body, as shown in Fig. 1, or Within the body, as shown in Fig. 2, of the drawings.

When it is desired to use the contents of the can the slip-cover C is removed andthe countersnnk portion of the thin or soft xed cover B is cut away on a line with the outer edge of the flange h or lower end of the inclined wa-ll h of the annular ring D by means of an ordinary pointed knife-blade, thus leaving the vertical portion of the cover B andthe annular ring lD united to the body of the can, which forms a smooth and firm trimmed edge, which supports and strengthens the upper edge of the canfand over which the paint-brush may be drawn without injury thereto. After the fixed cover has been removed the slip-cover can be used to cover and protect the contents of the can against the action ofthe atmosphere.

In a former patent of mine, No. 225,499, is shown a strengthening-ring located like the ring D, but having an inner upturned collar concentric with the edge of the can. This collar forms an opening of the same diameter throughoutitsdepth. Henceinusingthemandrel for holding the head of the can in seaming the former, passing through the opening,

presses upon the inner head, as before stated, and is liable to crush it in. geref this kind I have devised the ring herein described and shown, in which the inner opening, l, is smaller than the mouth Z; hence the To avoid any danmandrel is kept from pressing upon the inner parallel to and fits Within the body of the can, ro

head, B, and the latter is preserved intact in sheet-metal annular ring D, having its inner the process of seaming. opening, l, smaller than the mouth l', and

Having thus described my invention, what i slip-cover C, substantially as shown and de- 5 I claim as new, and desire to secure by Letters scribed.

Patent, is FRANCIS A. WALSH.
